Refueling
Important safety notes
GWARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is arisk of fire and explo-
sion.
You must avoid fire, open flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before refueling.
GWARNING
Fuel is poisonous and hazardous to health.
There is arisk of injury.
You must make sure that fuel does not come into contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.
If you or others come into contact with fuel,
observe the following:
RWash away fuel from skin immediately
using soap and water.
RIf fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
RIf fuel is swallowed, seek medical assis-
tance without delay.Don ot induce vomit-
ing.
RImmediately change out of clothing which
has come into contact with fuel.
GWARNING
Electrostatic buildupc an create sparks and
ignite fuel vapors. There is arisk of fire and
explosion.
Always touch the vehicle body before opening
the fuel filler flap or touching the fuel pump
nozzle. Any existing electrostatic buildupi s
thereby discharged.
Do not get into the vehicle again during the refu-
eling process. Otherwise, electrostatic charge
could build up again.
!Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the ignition
if you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel system. Even small amounts of the wrong fuel could
result in damage to the fuel system and the
engine. Notify aqualified specialist workshop
and have the fuel tank and fuel lines drained
completely.

lead to increased wear and damage to the
majorassemblies or the vehicle.
Aq ualified specialist workshop, e.g. an author-
ized Mercedes-Ben zCenter, will reset the
ASSYS TPLUS service interval display after the
service work has been carried out. You can also
obtain further information on maintenance
work,f or example.
Specia lservice requirements
The specified maintenance interval takes only
the normal operation of the vehicle into
account .Under arduous operating condition sor
increased load on the vehicle, maintenance
work must be carried out more frequently, for
example:
Rregular cit ydrivingw ith frequent intermediate
stops
Rif the vehicle is primarily used to travel short
distances
Ruse in mountainous terrain or on poor road
surfaces
Rif the engin eisoften left idling for long periods
Under these or similar conditions, have, for
example, the air filter, engin eoil and oil filter
replaced or changed more frequently. Under
arduous operating conditions, the tires must be
checked more often. Further information can be
obtained at aqualified specialist workshop, e.g.
an authorized Mercedes-Ben zCenter.
Driving abroad
An extensive Mercedes-Ben zService network is
also available in other countries. You can obtain
further information froma ny authorized
Mercedes-Ben zCenter.

mended and approved by Mercedes-Benz.
Washing th evehicle and cleaning the
paintwork
Automatic car wash
GWARNING
Braking efficienc yisreduced after washing
the vehicle. There is arisk of an accident.
After the vehicle has been washed, brake
carefully while paying attention to the traffic
condition suntil full braking power is restored.
!When DISTRONIC PLUS or the HOL Dfunc-
tion is activated, the vehicle brakes automat-
ically in certain situations.
To avoid damage to the vehicle, deactivate
DISTRONIC PLUS and the HOL Dfunction in
the followingors imilar situations:
Rwhen towingthe vehicle
Rin the car wash
!It is preferable to use car washes with
adjustable high-pressure pre-cleaning that
corresponds to the specification for the Cab-
riolet program. In car washes that use high
water pressures, there is arisk that asmall
amount of water may leak int othe vehicle.
